Birds in New York State Have Altered Their Migration Timing and Are Experiencing Different Thermal Regimes While Breeding or on Stopover from 2010 to 2015

Table 2

Migration timing changes and significant environmental temperature changes experienced by species showing a two-stopover migration strategy through Madison County. Migration patterns were determined using data from the Cornell lab of ornithology and Zuckerberg et al. [23].
